my setup is running really well with matr1x 20, i cant find any lag issues.

Smartass 210/840 live OC 105. using droidpfiles smartass battery profile with Frequencies adjusted to work with matr1x.
[Nexus S Android Development] d_phekt:
Of you flashed 20.0 over BM CM9 V3 you may need to reflash BM tweaks. I'm not positive, but the cleaning script in Matr1x kernel may have cleared out some of the tweaks.

v20 is blazing fast for me so far, no bad effects caused by 50hz yet. Slightly lower graphics numbers in antutu, yes, but nothing that can be seen in daily use. (Benchmarks do not always tell you how fast a sys really is in daily use.)

Maybe I should try playing need for speed, but no time for that now. :)
[Nexus S Android Development] atl4ntis:
Not sure if kernel related but sometimes my wireless becomes very slow like 10k/s and i need to shutdown and restart it. Could be the stochastic fair blue thing or deep idle? Beside this small issue love this kernel.

I flashed euroskank cm9 20120524 with 20120429 gapps and matri1x v 20bfs.

Plugged my usb into the phone and computer and copied the 122 mb file i just flashed both from my phone to the computer and from the computer to my phone. Both directions took just less than 2 minutes each way. That would equate to around 1 mb per sec. I would consider that acceptable.

Noob question. The phone starts to lag when battery drops to about 15-20% should I increase the arm voltage or the internal voltage?
[Nexus S Android Development] Skunk Ape1:
I'm not going to guess why your phone is lagging but I am willing to bet it has nothing to do with your battery level... :D

[Nexus S Android Development] insomnia48:
I have never said that I use BM tweaks. And another guy tested it on NS4G and he didn't have a problem either, so I guess it might be specific to the GSM ROM ;)

You mean the second is write and the first is read I suppose :p

There was never an issue with read anyway, but your write is not that far from the rest of us. We get less than 200KB/s and you get 800KB/s, which is four times more, but with the CM kernel we get about 1.8MB/s :confused:

Note: Same behaviour with latest nightly (24/05) as well :mad:

[Nexus S Android Development] :
When your battery gets low, it's voltage drops slightly. When the voltage first begins to get too low for the processor, it makes calculation errors. These errors can be corrected with further CPU cycles. This may account for the lag you experience when your battery is low.

When i did my battery benchmark on the effect of undervolting I saw that when the voltage was reduced past a certain point, power consumption began to increase instead of decreasing! Reduce it too much, and then it crashes.
[Nexus S Android Development] kalda01:
What does it mean for someone like me who never replaced a kernel before?

can someone explain which settings to adjust so the phone won't lag ?
[Nexus S Android Development] Blackcrx:
So in idiot terms. Under volting on a fresh battery saves power but under volting a low battery actually uses more power?

If that is true I should set up 2 sets of voltages in nstools. One set for 20%+ and another set for 20% and lower? Haha
[Nexus S Android Development] :
You could do that. I just keep the voltage higher all the time

I can see there is a battery change. Eg 6 hrs standby = 3% drop on v19.5... 6 hrs standby = 6% drop on v20. Well thats for me.. CM9 rom. But i can see a massive improvement on smoothness though. Its really really smooth and fast. Usually receiving, ending a call takes a few seconds, now it only takes less than one. Opening up contacts and browsing is much faster. I guess battery and the performance cancels each other out.

Edit: Nvm, battery is the same. Realised had my screen off profile to 800max 100min when its suppose to be 400max 100 min. Therefore Performance has improved ALOT

Now, as for the specific bug, it started hanging around after the 16/05 CM9 nightly, but it has been fixed since the 26/05 nightly. Maybe the ROM you are using is based on an earlier nightly.
[Nexus S Android Development] Lar5:
Yes, i guess it's a kernel problem.

I'm running AOKP m5 (before that stock ROM) and tried Matr1x kernel 19-20. The USB transfer was like your example - not acceptable.

A week ago i flashed Air kernel 4.2.

Then the USB write speed jumped to 1.5-2 MB/s.

It also gave me a much better Quadrant score. I/O score jumped from ~800 to ~4500 resulting in total score going from 1200 to 2000. :confused: The overall speed of the phone doesn't feel changed a lot going from Matr1x to Air kernel.

Matr1x kernel seems to have a few more features, but i find Air kernel better as long as it gives better USB write speed.
[Nexus S Android Development] DarkhShadow:
You know air kernel uses matr1x as a base right?

I have one small problem with matrix which isn't too bad but I do want to get rid of it. Whenever I turn my phone off and then boot it, my phone will freeze a few seconds into the boot animation then reboot. The boot animation is fine in the second run, and everything then goes smoothly. Strangely it doesn't happen when I reboot, only when I power off then boot.

I've tried different kernels and they don't have this problem. I tried different roms too (CM9, AOKP, rascream, BB) and I only get the problem with matrix. It's happened on v19.5 and v20. I tried increasing the voltages by 25 but that had no effect.

Is there a log I can get from this?

[Nexus S Android Development] :
Folks, seriously, if you need fast transfer speeds, reboot into recovery and do your transfer there.

Otherwise, check out Slim ICS which has MTP in the storage options... Speeds there will be at least five times faster when copying to the phone.

As for which kernel to use, i wouldn't base that choice on usb transfer speeds alone, especially when tests performed by different users give contradictory results, or have been interpreted badly.

[Nexus S Android Development] glennkaonang:
DI won't work properly on Slim ICS because krarvind doesn't disable bluetooth_adapter_quick_switch.

You need to edit the framework to get it working on Slim.

A little suggestion for you, try to raise the voltages a bit and see if the problem persists.
[Nexus S Android Development] :
Quadrant should not be used for serious benchmarking. None of its tests are consistent between roms. Even within the same ROM the results are horribly variable. Use antutu and sd card tester for a more realistic io comparison. Run the test multiple times to be sure of a reliable average result.
[Nexus S Android Development] caliban2:
Didle top-off doesn't work at all with quick switch enabled, so certainly not the problem.

Yeah, upping voltages could help (25mV-steps). Also, with ondemand setting min-freq to 200 could do the trick (Google's setting for ICS). I never had problems with 100mhz on lazy-gov, but got freezes listening to music after I switched to smartassv2. Solution: min-freq 100, sleep-ideal-freq 200. (Didle enabled)
[Nexus S Android Development] Harbb:
Didle will still be in effect, just in top=on mode which saves nothing measurable and i'm unsure of it's exact workings. Keep this in mind.
[Nexus S Android Development] caliban2:
Like I said, top off won't be working.

Top on is used while Bluetooth or GPS are active (meaning: in use, not just enabled). How it works exactly I have no idea, but it doesn't save any power. :)

Edit:

I stand corrected. GPS needs to be in use, for Bluetooth it's enough to be enabled to enter top on state. (Just tried)

I dont give a damn on what your problem is.. :mad:

Sent from my Nexus S®
[Nexus S Android Development] glennkaonang:
That's what I was trying to say, in Slim ICS, bluetooth_quick_switch_adapter is enabled (true), and that's the reason why you wouldn't get TOP=OFF.

In order to get TOP=OFF, it should be disabled (false).

I once tried editing the framework-res.apk myself to set bluetooth_quick_switch_adapter to false and I can confirm I got TOP=OFF with matr1x.
